UNTTED sTATEs PATENT oEEioE.

i DAVID SABINS, OF LANCASTER, PENNSYLVANIA.

Specification of Letters Patent 1\To.` 3,498, dated March 20, 1844:.`

To all whom it mag/concern Be it known that I, D. SABINS, ofthe city ofLancaster, in thecounty of Lancaster and State of Pennsylvania, haveinvented certain new and useful Improvements in the Manner ofConstructing Trusses for the Cure or Relief of Inguinal Hernia; `and Ido hereby declare that the following is a full and exact descriptionthereof.

The pad, or pads, of my improved truss are so connected with the mainspring as to allow greater freedom of motion to the body, and, in everyposition, to cause it to press more equally than any of those previouslyconstructed, so far as I have had an opportunity of becoming acquaintedwith! them.

In the accompanying 4drawing Figure 1, is a representation of the mainspring and pads of a double truss, these parts being sho-wn without thecovering and strap which are to be appended to it when finished. Thepads A, A, which maybe made of wood, or other material, are to behollowed out on their backs, as shown at B, B, to receive a jointedlink, which at one end is attached to the bridge piece C, C, of the pad,and at the other tostripsof iron, or of steel, e, c', which are affixedto ,the spring by a regulating screw a; the ends of these strips beingcurved in such manner as to enter the cavities B, B, and thereby toadapt them to the intended purpose. The bridge pieces, C, C, have slotsin their ends, as shown at b, to receive the tightening screws c, c;these allow of the adjusting of the pad by moving the bridge piecesendwise, in such a man-e ner as that the link attached thereto may bearupon it out of its center, so that it shall exert its greatest pressurewhere it is most required, which is usually on the lower part thereof.

Fig. 2, represents one of the strips e,

uwhich is shown ascurved at its end, f, so as to enter the cavity, B, inthe back of the` pad; g, is the link connected to this strip e,

and to the bridge piece, C, by two joint pins;` by which device anylexure of the body is admitted without producing the slightest tendencyto displace the pad, or to cause an unequal pressure thereof. `At theinner end of the strip e, there is a lip which enters a slot in thepiece next above it, and

preserves it from lateral Amotion; by this arragement, andv by means ofthe regulating screw, a, the distance of the two padsA from each othermay be regulated at pleasure; or when one pad only is required, by thetaking out of this screw, the inner pad,`with its strip, e, may beremoved; the same device allows, also, of the lengthening, orshortening, of the main spring, to adapt the pad to the requirements ofthe patient.

Having thus, fully described the nature of my improvements in the trussfor the cure, or relief, 4of inguinal hernia, and shown the manner inwhich I construct the same, what I claim therein as new, and desire tosecure by Letters Patent, is

l. The manner herein set forth of connecting the pad, or pads, to theprincipal spring by the means of a double jointed link,

contained within a cavity on the back part of the pad, arranged andoperating as herein described.

2. I also claim, in combination therewith, the manner of adjusting thepressure of the pad, by the `aid of the regulating bridge piece, bymeansof which the link may be made to bear on either side of the centerof the pad, or pads, as may be requisite.
